Summary
THIS DOCUMENT, IN CONJUNCTION WITH THE INFORMATION PROVIDED WITHIN THE MANUALS LISTED IN TABLE 1 PROVIDES INSPECTION AND REPAIR GUIDELINES FOLLOWING THE MALFUNCTION OF AN XPI FUEL PUMP PUMPING PLUNGER AND/OR ROLLER TAPPET ASSEMBLY. THE LEVEL OF PROGRESSIVE DAMAGE TO THE FUEL PUMP AND OTHER ENGINE COMPONENTS WILL VARY WITH EVERY INCIDENT; HOWEVER, THE REPAIR DIRECTION WILL DEPEND ON ONLY A FEW KEY CRITERIA. PREVIOUS VERSIONS OF THIS DOCUMENT PROVIDED SPECIFIC REPAIR DIRECTIONS ACCORDING TO THE VINTAGE OF THE FUEL PUMP AND TYPE OF PUMPING PLUNGERS. REPAIR DIRECTIONS HAVE NOW BEEN MADE COMMON AND APPLY TO ALL FUEL PUMPS REGARDLESS OF VINTAGE, PUMPING PLUNGER TYPE, OR TAPPET ROLLER ASSEMBLY TYPE. THIS IS A REVISION TO A PREVOUSLY SUBMITTED COMMUNICATION.

This document, in conjunction with the information provided within the manuals listed in the
table above, provides the inspection and repair practice when ceramic plungers are found to
be fractured (see Figure 1) and/or tappet roller damage is found on fuel pumps with ceramic
plungers (see Figure 2). Ceramic plungers can be identified by their white color. See
Procedure 005-227 in the Associated Procedures Table for removal of the fuel pump head.

Figure 2: Fuel Pump Tappet Roller Assemblies
If the ceramic plungers are fractured (see Figure 1), but no damage is found on the fuel pump
tappet rollers (see Figure 2), no further inspection is needed. Perform the following steps for
the appropriate engine (ISX15 CM2250, QSX15 CM2250 ECF, ISX12/ISX11.9 CM2250, or
QSX11.9 CM2250 ECF):
1. Replace the fuel pump. See Procedure 005-016 in the Associated Procedures Table.
a. For ISX15 CM2250 or QSX15 CM2250 ECF: Refer to TSB110064 (New TwoCylinder High-Pressure Fuel Pump Assembly) if replacing a three-cylinder twopiston pump with a two-cylinder pump.
b. For ISX15 CM2250 or QSX15 CM2250 ECF: New fuel lines are required if
replacing a fuel pump gear pump with bottom mount fuel lines. See Technical
Service Bulletin, New Fuel Pump Gear Pump with Revised Fuel Line Locations,
TSB130044.
2. Change the engine lubricating oil and lubricating oil filter. See Procedure 007-013 in the
Associated Procedures Table.
If the fuel pump tappet rollers are damaged (see Figure 2), perform the following steps for the
appropriate engine (ISX15 CM2250, QSX15 CM2250 ECF, ISX12/ISX11.9 CM2250, or
QSX11.9 CM2250 ECF):

1. Replace the fuel pump. See Procedure 005-016 in the Associated Procedures Table.
a. For ISX15 CM2250 or QSX15 CM2250 ECF: See Technical Service Bulletin, New
Two-Cylinder High-Pressure Fuel Pump Assembly, TSB110064, if replacing a
three-cylinder two-piston pump with a two-cylinder pump.
b. For ISX15 CM2250 or QSX15 CM2250 ECF: New fuel lines are required if
replacing a fuel pump gear pump with bottom mount fuel lines. See Technical
Service Bulletin, New Fuel Pump Gear Pump with Revised Fuel Line Locations,
TSB130044.
c. For ISX15 CM2250 engines not covered by warranty, there is an option to use a
fuel pump short block service kit. See Technical Service Bulletin, New Fuel Pump
Short Block Service Kit, TSB150033.
2. Drain the engine lubricating oil and remove the lubricating oil filter. See Procedure 007013 in the Associated Procedures Table.
3. Thoroughly clean the oil cooler housing. See Procedure 007-003 in the Associated
Procedures Table.
4. Replace the lubricating oil cooler element. See Procedure 007-007 in the Associated
Procedures Table.
5. Replace the oil filter bypass valve. See Procedure 007-014 in the Associated Procedures
Table.
6. Replace the lubricating oil thermostat. See Procedure 007-039 in the Associated
Procedures Table.
7. Install a new lubricating oil filter. See Procedure 007-013 in the Associated Procedures
Table.
8. Fill the engine with new lubricating oil.
9. Perform an aftertreatment diesel particulate filter regeneration. See Procedure 014-013
in the Associated Procedures Table.
10. Perform a second lubricating oil and lubricating oil filter change. See Procedure 007-013
in the Associated Procedures Table.
CAUTION
Immediately upon removal of the lubricating oil cooler assembly, a plug must be inserted
into the housing and cylinder block oil passage drillings. Failure to insert the oil passage
plug can result in a bearing failure, crankshaft failure, or both.
CAUTION
Do not allow dirt or foreign material to enter oil passages in the cylinder block when cleaning
the gasket sealing surfaces. Connecting rod bearing failures can be caused if debris is
introduced into the cylinder block or lubricating oil cooler housing oil passages. Therefore,
use of power tools combined with abrasive pads to clean gasket surfaces is not
recommended.
